Installation Inna-Dor is delivered completely factory assembled for the fastest and easiest on site installation. The doorset could be heavy depending on the specification ordered so will require more than one person to move on site and adjust into place for fitting.
The outer door sub frame has an adjustable frame to provide adjustments of up to 30mm and allow out of square openings to be accommodated easier.
Some door specifications will require specific methods, sub frames and fixings to be used to comply with their certification. General purpose steel doorsets can use the best fixings for the substrate you are fixing to.
WarrantyAll Inna-Dor steel doorsets manufactured using a base material of ‘Magnelis’ carry a 10 year anti-corrosion warranty in any locations classed as C1 – C3.
Any locations classed as C4 or C5 would carry a 5 year and 3 year warranty respectively. Anti-corrosion warranty applies to the door leaf only unless we are informed prior to quotation
and manufacturing and an additional protection is offered for components not available in magnelis such as the vision panels, louvre panels, etc…
Any doorsets manufactured in Aluzinc carry a 24 month anti-corrosion warranty unless an enhanced PPC finish is requested and applied.
All doorsets carry a 24 month warranty against manufacturing defects.
All warranties are subject to site maintenance being carried out at regular intervals as outlined in the O&M manual. Manufactured entirely by Robust Doors in the UK.
MeasureA steel doorset is always ordered by the OVERALL dimensions including the door leaf and outer sub fixing frame with no tolerances allowed for. Most people would generally allow 5mm tolerance all the way around the door, but it all depends on how square or true your aperture is on site.
This means if your structural opening size is measured as 1000mm width and 2100mm height the door and frame ought to be 990mm wide and 2090mm high with the frame and any threshold included.
Always measure the top, middle and bottom of your aperture width and the left and right hand side for the height and if possible do a measure to make sure the opening is square as well.
Always use millimetres for measuring as this is how we relay back the ordering dimensions to you for checking and approving a drawing for your order.
The Robust Inna-Dor does have an adjustable fitting frame to take up to 30mm of tolerance into account which helps when the opening is not square.
